Tungaloy TNGG160408L-P GH110 Turning Insert

PVD Coated GH110 Grade | Precision -P Chipbreaker | 0.8mm Left-Hand Radius

What is the most reliable PVD coated insert for high-wear steel finishing?

The Tungaloy TNGG160408L-P GH110 is a premium left-hand PVD coated carbide insert engineered for high-precision finishing in ISO P (Steel) and ISO K (Cast Iron). Featuring the advanced GH110 grade, this tool offers exceptional flank wear resistance and edge toughness, ensuring dimensional stability across long production cycles. The 0.8mm corner radius (08) provides a robust cutting edge capable of higher feed rates while maintaining superior surface integrity. 100% Made in Japan, it is the industrial benchmark for CNC operators who require repeatable precision in demanding steel turning applications.

GH110 High-Wear PVD

A specialized PVD coating with extreme hardness. It protects the sharp cutting edge against abrasive wear, making it ideal for high-carbon steels and cast iron.

-P Finishing Geometry

The -P chipbreaker is optimized for light depths of cut. It facilitates excellent chip flow, preventing surface marring and keeping the workpiece clear of stringy chips.

0.8mm Robust Radius

Balanced for finishing, the 0.8mm radius offers increased edge strength compared to finer radii, allowing for stable machining even in slightly unstable setups.

3. Technical Data: Metric vs. Imperial Standards

Feature	Metric (ISO)	Imperial (ANSI)
Standard Model	TNGG160408L-P	TNGG 332L-P
Inscribed Circle (IC)	9.525 mm	3/8"
Thickness (S)	4.76 mm	3/16"
Corner Radius (RE)	0.8 mm	1/32"

Recommended Parameters for GH110

Cutting Speed (Vc): 80 - 180 m/min (Balanced Performance)
Feed Rate (f): 0.10 - 0.25 mm/rev (Standard Finishing)
Depth of Cut (ap): 0.2 - 1.2 mm

*B2B Pro-Tip: The 0.8mm radius is ideal for the final finishing pass in batches where dimensional tolerance is more critical than ultra-high gloss.*

4. Primary Applications

Precision finish turning of carbon and alloy steels.
Continuous finishing of cast iron (ISO K) parts.
Final pass machining for large batches of automotive pins and shafts.
Excellent for boring bars where chip control is restricted.

5. Tool Compatibility

Standard TN** 1604 interface. Pairs specifically with WTJNL or MTJNL Left-hand external holders. Also optimized for S-WTJNL internal boring bars.

Global CNC Machinist Feedback

⭐⭐⭐⭐⭐ "Consistent Edge Quality" - Robert H., USA
"The GH110 grade is incredibly stable. We use the 0.8mm radius for finish passes on alloy shafts and the tool life is outstanding."

⭐⭐⭐⭐⭐ "Sharp and Reliable" - Klaus M., Germany
"Original Tungaloy quality. Very good chip control even on light finishing passes. One of the best PVD inserts for steel."

⭐⭐⭐⭐ "Great for Long Batches" - Tan L., Vietnam
"Maintains dimensional accuracy throughout the run. Beyond team provided fast delivery and perfect technical advice."

⭐⭐⭐⭐⭐ "Top Grade Finishing" - Marco S., Italy
"The -P breaker is perfect for our light cuts. No chip bird-nesting issues. Highly professional Japan-made tool."

⭐⭐⭐⭐⭐ "Best B2B Source" - Arjun V., India
"Genuine factory-sealed boxes. Best support for our CNC lathe setup from the Beyond team."

8. FAQ - Precision Tooling Support

Q: When should I choose GH110 over a cermet insert?

A: Use GH110 (PVD Carbide) for finishing where the material is abrasive or if the setup has slight vibration. It is tougher and more resistant to edge chipping than cermet.

Q: Can this insert be used in a standard Right-hand holder?

A: No, this is a Left-hand (L) insert. It must be used with a Left-hand tool holder (WTJNL) for correct chipbreaker performance and edge orientation.

Tech Tip: Surface Excellence with PVD Carbide

Maintain a stable feed rate and ensure proper coolant flow to maximize the life of the **GH110** coating. For the highest surface gloss, keep the cutting speed near the upper limit. **Tungaloy Japan** - Leading the way in precision finishing technology.

Technical FAQ & Buying Guide

Are your carbide inserts interchangeable with major brands like Sandvik, Iscar, or Kennametal?

Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.

How do I choose the correct insert grade and chipbreaker for machining Stainless Steel (M) vs. Carbon Steel (P)?

We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:

For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.

What are the recommended cutting speed (Vc) and feed rate (f) parameters to maximize tool life?

The optimal cutting parameters vary depending on the workpiece hardness and operation type:

For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.

Do you offer bulk discounts or wholesale pricing for machine shops and distributors?

Yes, we support machine shops, distributors, and global buyers with tiered wholesale pricing and competitive volume discounts. We also provide OEM custom manufacturing solutions for tool holders and carbide inserts based on your technical drawings. Contact our team to request a quick B2B quotation.

What is your international shipping policy and typical lead time for orders?
